Beit known thatI, HENRY C. KARLsoN, a. citizen 'of the United States,'and aresizlent'of Hasbrouck Heights, inthe county o fergen and Stateyof New Jersey, have invented ai certain new and useful Turbine, ofwhich the This invention relates vto .turbine-Wheels;

and its objects comprisevmeans by which the` propelling fluidfra'turbine-wheel is used expansively, means vto easily reverse therotaf.
